I would also go with NestJS. I would say Java is unnecessarily complicated and limited. And Python is not typed. TypeScript is powerful and typed and goes well with NestJS, especially using RxJS.

Django does not enforce backend-frontend separation, which probably was a good thing back in the days, but not anymore. But on the other hand enforces the project structure to you, which I don't like.

TypeScript provides type safety and is preferred over JavaScript in all cases. In addition to type safety, one has a better syntax that helps with the readability of the code, as well as maintainability.
